Abstract
The invention discloses refractory insulating wallpaper containing a modified acrylic resin emulsion coating. A resin adhesive adopted in coating slurry used by the wallpaper is a cellulose acetate-copolymerized and modified water-based acrylic resin emulsion. The resin emulsion is stable in performance, and does not contain chronic volatile toxic compounds such as formaldehyde; the formed coating is smooth and elastic and has water-resistant, anti-fouling and antibacterial functions; due to a porous fiber prepared by mixing hydrophobically modified expanded perlite micro powder and polylactic acid, the air permeability of the coating can be effectively improved; the coating is endowed with an excellent refractory insulating efficiency; the novel wallpaper is relatively low in production cost and is energy-saving and environment-friendly; indoor air can also be improved in an assist manner; and the sterilization effect is reached.
